TO ALE WHOM IT MAY CONCERN:

Be it known that I, Josfi MARIA BLANCO Y NUi'w, of Havana, in the Island of Cuba, have invented certain new and useful Improvements in Preserving Fruits, &c., from decay; and I dohereby declare that the follow-' ing is a. full, clear, and exact description thereol', reference being had to the accompanying drawings, makiri-g part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in preparing apuste composed of plaster of Paris, mixed with salt and water dis solved, and then encasing the fruit or vegetables to be preserved, each one separately, with a. thick coating of this paste, which soon sets or dries, and thereby encases the article in an air-tight case or shell, by which it can be preserved for an indefinite length of time.

It is obvious that a paste composed of plaster or clay, mixed with water and any suitable gum or resin, may be used in the same manner, but I prefer the use of the plaster and salt water, as thesalt has also a preservative efiect chemically, and this acting with the plaster to form a shell, which operates mechanically to exclude the air, I find to operate in a. very superior manner.

What I claim, is

The process of preserving fruits and vegetables, substantially as herein described.
